Technical Summary
The DSP56F803EVM is designed as a versatile Digital Signal Processor, (DSP),
development card for developing real-time software and hardware products to support a
new generation of applications in digital and wireless messaging, servo and motor control,
digital answering machines, feature phones, modems, and digital cameras. The power of
the 16-bit DSP56F803 DSP, combined with the on-board 64K
×
16-bit external program
static RAM (SRAM), 64K
×
16-bit external data SRAM, CAN interface,
Hall-Effect/Quadrature Encoder interface, motor zero crossing logic, motor bus
over-current logic, motor bus over-voltage logic and parallel JTAG interface, makes the
DSP56F803EVM ideal for developing and implementing many motor controlling
algorithms, as well as for learning the architecture and instruction set of the DSP56F803
processor.
